The oil barrel 7 is transported to the processing tunnel 11, the first barrel holding and turning mechanism 3 is arranged on the feed conveying mechanism 2, and is used to turn the oil barrel 7 conveyed by the feed conveying mechanism 2 by 180 degrees. The pushing mechanism 4 is arranged in the processing tunnel 11, and is used to push the oil barrel 7 located in the processing tunnel 11 to move along the processing tunnel 11. The discharge conveying mechanism 5 is arranged at the other end of the processing tunnel 11, and is used to receive the oil barrel 7 coming out of the processing tunnel 11 and output the oil barrel 7. The second barrel holding and turning mechanism 6 is arranged on the discharge conveying mechanism 5, and is used to turn the oil barrel 7 conveyed by the discharge conveying mechanism 5 by 180 degrees.

[0036] The processing tunnel 11 is a hollow structure with two ends open. In one embodiment, the processing tunnel 11 includes a bottom plate and a box body arranged on the bottom plate, and a plurality of oil leakage holes are opened on the bottom plate. The bottom plate is preferably a support grid.

[0037] In one embodiment, the pushing mechanism 4 includes a first conveying assembly 41, a second conveying assembly 42, a first manipulator 43, a second manipulator 44 and a plurality of transverse baffles 45. A first longitudinal baffle 14 is provided at the top of the tunnel. The first longitudinal baffle 14 divides the interior of the processing tunnel 11 into a first area and a second area. The first conveying assembly 41 is arranged at the top of the first area, and the second conveying assembly 42 is arranged at the bottom of the second area. The second conveying assembly 42 includes a first driving wheel 421, a first driven wheel 422, a first conveying chain 423 and a first driving unit. The first driving wheel 421 and the first driven wheel 422 are arranged at intervals. The first conveying chain 423 is wound around the first driving wheel 421. On the driving wheel 421 and the first driven wheel 422, the first driving unit is connected to the first driving wheel 421 for driving the first driving wheel 421 to rotate. The first conveying chain 423 is provided with a plurality of grooves 424 for installing the transverse baffle 45. The structure of the first conveying assembly 41 is the same as that of the second conveying assembly 42. The first manipulator 43 and the second manipulator 44 are respectively arranged on both sides of the second conveying assembly 42. The first manipulator 43 is used to install the transverse baffle 45 on the second conveying assembly 42 to the first conveying assembly 41, and the second manipulator 44 is used to install the transverse baffle 45 on the first conveying assembly 41 to the second conveying assembly 42. The number of transverse baffles 45 can be determined according to the length of the processing tunnel 11 and the diameter of the oil barrel 7. Each transverse baffle 45 is used to push an oil barrel 7 located in the processing tunnel 11, that is, the space between two adjacent transverse baffles 45 can place an oil barrel 7. The transverse baffle 45 is used to provide the power for the oil barrel 7 to move, and can also limit the position of the oil barrel 7 to prevent the oil barrel 7 from overturning. When in use, a number of transverse baffles 45 are first installed on the groove 424 of the second conveying component 42 at the top of the first conveying chain 423. When an oil barrel 7 is conveyed into the processing tunnel 11, the transverse baffle 45 closest to it is clamped by the first manipulator 43, and then the clamped transverse baffle 45 is installed on the groove 424 of the first conveying component 41, so that the transverse baffle 45 is located behind the forward direction of the oil barrel 7, and then the first driving unit of the first conveying component 41 is used to drive the corresponding first driving wheel 421 and the first conveying chain 423 to rotate, so that the oil barrel 7 is pushed to move by the transverse baffle 45 installed on the first conveying chain 423, so that the oil barrel 7 moves forward a distance of the diameter of the oil barrel 7, leaving the entrance position of the processing tunnel 11 vacant, and reserving space for subsequent oil barrels 7 to enter the processing tunnel 11. At the same time, the first driving unit of the second conveying component 42 is used to drive the corresponding first active wheel 421 and the first conveying chain 423 to rotate, so that the groove 424 on the second conveying component 42 is moved forward, thereby driving the transverse baffle 45 on the second conveying component 42 to move, so that the first robot 43 can clamp the transverse baffle 45 again, and a groove 424 will be vacated at the rear end of the second conveying component 42.After a subsequent oil barrel 7 enters the processing tunnel 11, the above process is repeated, and the transverse baffle 45 on the first conveying assembly 41 pushes the subsequent oil barrel 7 to move in the processing tunnel 11 at a time, and one oil barrel 7 is pushed by one transverse baffle 45. When the oil barrel 7 is pushed out of the processing tunnel 11, the transverse baffle 45 located at the front of the first conveying assembly 41 is clamped by the second manipulator 44, and the transverse baffle 45 is installed on the empty groove 424 at the rear end of the second conveying assembly 42, and the cycle is repeated in sequence to push the oil barrel 7 in the processing tunnel 11, and the height of the processing tunnel 11 can be lowered. In one embodiment, the opening of the groove 424 is smaller than the bottom of the groove 424, and one end of the transverse baffle 45 is provided with a horizontal plate for inserting into the groove 424. The opening of the groove 424 is small, so that when the horizontal plate on the transverse baffle 45 is inserted into the groove 424 on the first conveying component 41, the horizontal plate can cooperate with the groove 424 so that the transverse baffle 45 is suspended on the groove 424, and when the horizontal plate on the transverse baffle 45 is inserted into the groove 424 on the second conveying component 42, the horizontal plate can make the transverse baffle 45 stand stably on the second conveying component 42.

[0038] In one embodiment, the first manipulator 43 and the second manipulator 44 are both provided with a support frame 46, and a plurality of suction cups 47 are provided on the support frame 46, and an air pump connected to the suction cups 47 is provided on the suction cups 47. When the suction cups 47 are required to adsorb the transverse baffle 45, the air pump is used to evacuate air to create a vacuum area, so that the suction cups 47 are close to the transverse baffle 45, and adsorb the transverse baffle 45 under the action of atmospheric pressure. When the suction cups 47 are required to release the transverse baffle 45, the air pump is used to supply air for a period of time to release the suction cups 47. The first manipulator 43 and the second manipulator 44 both adsorb the transverse baffle 45 through the suction cups 47, thereby driving the transverse baffle 45 to move.

[0039] In one embodiment, a second longitudinal baffle 15 is provided at the top of the processing tunnel 11, and a passage for moving the oil barrel 7 is formed between the second longitudinal baffle 15 and the first longitudinal baffle 14. The second longitudinal baffle 15 is close to the side wall of the processing tunnel 11, and plays a role in limiting the movement of the oil barrel 7 to prevent the oil barrel 7 from tipping over, and at the same time, it can prevent the oil barrel 7 from directly contacting the side wall of the processing tunnel 11, thereby avoiding damage to the processing tunnel 11.

[0040] In one embodiment, a plurality of rollers 16 are provided at intervals at the bottom of the processing tunnel 11 along the length direction of the processing tunnel 11. The rollers 16 are cylindrical in shape as a whole, which can reduce the friction between the oil drum 7 and the bottom of the processing tunnel 11, thereby reducing the conveying resistance.

When the oil barrel 7 is transported to the position of the first barrel holding and turning mechanism 3, the oil barrel 7 is clamped by the third manipulator 34, and then the rotating shaft is driven to rotate 180 degrees by the first driving assembly to drive the third manipulator 34 and the oil barrel 7 to turn 180 degrees, so that the barrel mouth of the oil barrel 7 faces downward, and then the third manipulator 34 releases the oil barrel 7 after turning 180 degrees, and the oil barrel 7 continues to be transported to the processing tunnel 11 by the feeding and conveying mechanism 2. The third manipulator 34 is provided with a pressure sensor, which can monitor the pressure of the manipulator clamping the oil barrel 7 to meet the different force requirements of the third manipulator 34 when clamping the oil barrel 7.

The first driving component can adopt an existing driving device, which will not be repeated again.

[0042] In one embodiment, the first barrel holding and turning mechanism 3 includes a gantry 31, a first support rod 32, a second support rod 33, a second drive assembly, a third drive assembly, and a third manipulator 34 for clamping or releasing the oil barrel 7. The two ends of the first support rod 32 are respectively slidably arranged on the two vertical rods of the gantry 31. The second drive assembly is connected to the first support rod 32 and is used to drive the first support rod 32 to move up and down along the vertical rod of the gantry 31. The second support rod 33 is arranged on the first support rod 32 and can move along the circumference of the first support rod 32. The third drive assembly is connected to the second support rod 33 and is used to drive the second support rod 33 to move along the circumference of the first support rod 32. The third manipulator 34 is arranged on the second support rod 33. The third manipulator 34 is provided with a pressure sensor.

According to the specifications of the oil barrel 7, the first support rod 32 is driven up or down by the second driving assembly, so that the third manipulator 34 can clamp the middle part of the oil barrel 7 to adapt to the oil barrels 7 of different specifications, and can avoid the oil barrel 7 from interfering with the gantry 31, the feeding conveying mechanism 2 or the discharging conveying mechanism 5. After the adjustment is completed, when the oil barrel 7 is transported to the position of the first barrel holding and turning mechanism 3, the oil barrel 7 is clamped by the third manipulator 34, and then the second support rod 33 is driven by the third driving assembly to move along the circumference of the first support rod 32 to drive the third manipulator 34 and the oil barrel 7 to turn 180 degrees, so that the barrel mouth of the oil barrel 7 faces downward, and then the third manipulator 34 releases the oil barrel 7 after turning 180 degrees, and the oil barrel 7 continues to be transported to the processing tunnel 11 by the feeding conveying mechanism 2.

Similarly, for the discharge conveying mechanism 5, the second driving unit drives the second driving wheel 21 to rotate, and the rotation of the second driving wheel 21 drives the second conveying chain 23 to rotate, thereby driving the oil barrel 7 to move through the second conveying chain 23, and the oil barrel 7 is output and recovered.

In one embodiment, a heat preservation layer is provided on the outside of the storage tank 13, and a second heating component is provided on the storage tank 13. The old frying oil in the storage tank 13 can be prevented from solidifying.

[0045] The following is a brief description of the use of the utility model frying old oil pretreatment device:

[0046] After the old frying oil is collected and solidified by the oil barrel 7, it is manually opened and sent to the second conveying chain 23 of the feeding conveying mechanism 2. When the oil barrel 7 is conveyed to the position of the first barrel holding and turning mechanism 3, the oil barrel 7 is turned 180 degrees by the first barrel holding and turning structure, so that the barrel mouth of the oil barrel 7 faces downward, and then the feeding conveying mechanism 2 continues to convey the oil barrel 7 and inputs the oil barrel 7 into the processing tunnel 11. The processing tunnel 11 uses the first heating component for intermittent heating, and the internal temperature is controlled at 70-80°C. The first heating component can use steam or electric, hot air and other heating devices.

[0047] After the oil barrel 7 enters the processing tunnel 11, the pushing mechanism 4 pushes the oil barrel 7 forward slowly, so that the time the oil barrel 7 stays in the processing tunnel 11 is maintained at one to two hours. Due to the high temperature inside the processing tunnel 11, the old frying oil melts along with the old oil on the barrel wall of the oil barrel 7, falls into the oil collecting funnel 12 through the oil leakage hole at the bottom of the tunnel, and is collected by the oil collecting funnel 12 and stored in the storage tank 13. The storage tank 13 is provided with a second heating component and a heat preservation layer. After the old frying oil is completely melted, the first delivery pump 19 and the second delivery pump 110 are used to take oil at different positions of the storage tank 13, so that the impurities of the old frying oil can be separated, and the old frying oil of different levels can be delivered to the subsequent processing section for processing.

[0048] The oil barrel 7 after pouring out the old frying oil is pushed out from the processing tunnel 11 and enters the second conveying chain 23 of the discharging conveying mechanism 5. When the oil barrel 7 is conveyed to the position of the second barrel holding and turning mechanism 6, the oil barrel 7 is turned 180 degrees by the second barrel holding and turning structure, so that the barrel mouth of the oil barrel 7 faces upward, and the oil barrel 7 is output from the discharging conveying mechanism 5 in the forward direction, and then the barrel cover of the oil barrel 7 is manually covered, and the oil barrel 7 enters the next recycling cycle.

[0049] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Therefore, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
